Firazyr (icatibant) is used to treat attacks of an immune system disorder that occurs in adults known as hereditary angiodema.
Firazyr has been reported to cause allergic reactions similar to the signs of hereditary angiodema including hives, breathing trouble and facial swelling.
Do not use more than three Firazyr injections within a 24-hour period. Call your doctor if your symptoms do not improve, or if they get worse after using this medication.
Firazyr is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
